E.g. vs I.e.
What's the difference?
Two Latin abbreviations that look similar and get swapped all the time — but they mean different things. One gives examples; the other clarifies.
Quick answer
e.g. = "for example" (a sample from many). i.e. = "that is / in other words" (a precise restatement). Examples → e.g.; clarification → i.e.
Compared side by side
(abbreviation of Latin "exempli gratia") for example — introduces one or more examples.
- “Bring a snack, e.g. fruit or nuts.”
- “Citrus fruits, e.g. oranges and lemons, are high in vitamin C.”
(abbreviation of Latin "id est") that is; in other words — restates or clarifies.
- “The deadline is the end of the week, i.e. Friday.”
- “It doubled, i.e. went from 10 to 20.”
How to remember it
e.g. = Example Given. i.e. = In Essence (that is). Use e.g. before a sample, i.e. before a restatement. Both usually take a comma after.
Frequently asked
What's the simplest way to remember?
e.g. = "example given." i.e. = "in other words." If you could add "such as," use e.g.; if you could add "in other words," use i.e.
Do they need periods and a comma?
In American English, keep the periods (e.g., i.e.) and follow with a comma. British style often drops the comma. Either way, don't italicise them — they're fully at home in English now.
